Legal claims defining the scope of protection, as filed with the USPTO.
1. A computer-implemented method for performing backup operations, the method comprising: receiving, at a virtual machine (VM) management server, a request from a backup application server to back up a first VM, wherein the VM management server manages a plurality of VMs hosted by a plurality of host systems, and wherein the backup application server manages backup operations of a plurality of storage systems; determining at the VM management server a first of the host systems based on the request, wherein the first host system hosts the first VM; and transmitting a first request from the VM management server to a VM monitor (VMM) of the first host system hosting the first VM via a VM application programming interface (VM API) over a network, the first request requesting the VMM to capture a VM snapshot representing a consistent state of the first VM, wherein in response to determining that the consistent state of the VM has been captured, a second request is transmitted to a first storage system associated with the first host system to send one or more VM disk images associated with the consistent state of the first VM to a second storage system over the network, wherein the first host system is a separate system communicatively coupled to the first storage system.
2. The method of claim 1 , wherein the VM management server maintains VM configuration information of the plurality of VMs hosted in the plurality of host systems.
3. The method of claim 1 , wherein the consistent state of the first VM is generated based on the VM snapshot captured by the VMM.
4. The method of claim 1 , wherein the second storage system is a separate system with respect to the backup application server.
5. The method of claim 4 , wherein the one or more VM disk images associated with the consistent state of the first VM are disk snapshots stored at the first storage system.
6. The method of claim 5 , wherein the backup application server requests the VMM via the VM API to delete the VM snapshot taken after the disk snapshots have been backed up from the first storage system to the second storage system.
7. The method of claim 1 , wherein the first storage system sends only segments of the requested VM images that have not been stored in the second storage system.
8. The method of claim 1 , wherein the second storage system invokes a deduplicated segment storage engine to store segments of the requested VM disk images that have not been stored in the second storage system.
9. The method of claim 1 , wherein the backup application server parses the received VM disk images associated with the first VM to determine information about files contained in the received VM disk images and saving the determined file information in a backup catalog.
10. A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising: receiving, at a virtual machine (VM) management server, a request from a backup application server to back up a first VM, wherein the VM management server manages a plurality of VMs hosted by a plurality of host systems, and wherein the backup application server manages backup operations of a plurality of storage systems; determining at the VM management server a first of the host systems based on the request, wherein the first host system hosts the first VM; and transmitting a first request from the VM management server to a VM monitor (VMM) of the first host system hosting the first VM via a VM application programming interface (VM API) over a network, the first request requesting the VMM to capture a VM snapshot representing a consistent state of the first VM, wherein in response to determining that the consistent state of the VM has been captured, a second request is transmitted to a first storage system associated with the first host system to send one or more VM disk images associated with the consistent state of the first VM to a second storage system over the network, wherein the first host system is a separate system communicatively coupled to the first storage system.
11. The non-transitory machine-readable medium of claim 10 , wherein the VM management server maintains VM configuration information of the plurality of VMs hosted in the plurality of host systems.
12. The non-transitory machine-readable medium of claim 10 , wherein the consistent state of the first VM is generated based on the VM snapshot captured by the VMM.
13. The non-transitory machine-readable medium of claim 10 , wherein the second storage system is a separate system with respect to the backup application server.
14. The non-transitory machine-readable medium of claim 13 , wherein the one or more VM disk images associated with the consistent state of the first VM are disk snapshots stored at the first storage system.
15. The non-transitory machine-readable medium of claim 14 , wherein the backup application server requests the VMM via the VM API to delete the VM snapshot taken after the disk snapshots have been backed up from the first storage system to the second storage system.
16. The non-transitory machine-readable medium of claim 10 , wherein the first storage system sends only segments of the requested VM images that have not been stored in the second storage system.
17. The non-transitory machine-readable medium of claim 10 , wherein the second storage system invokes a deduplicated segment storage engine to store segments of the requested VM disk images that have not been stored in the second storage system.
18. The non-transitory machine-readable medium of claim 10 , wherein the backup application server parses the received VM disk images associated with the first VM to determine information about files contained in the received VM disk images and saving the determined file information in a backup catalog.
19. A data processing system operating as a virtual machine (VM) management server, comprising: a processor; and a memory storing instructions, which when executed by the processor, cause the processor to perform operations, the operations including receiving a request from a backup application server to back up a first VM, wherein the VM management server manages a plurality of VMs hosted by a plurality of host systems, and wherein the backup application server manages backup operations of a plurality of storage systems; determining a first of the host systems based on the request, wherein the first host system hosts the first VM; and transmitting a first request to a VM monitor (VMM) of the first host system hosting the first VM via a VM application programming interface (VM API) over a network, the first request requesting the VMM to capture a VM snapshot representing a consistent state of the first VM, wherein in response to determining that the consistent state of the VM has been captured, a second request is transmitted to a first storage system associated with the first host system to send one or more VM disk images associated with the consistent state of the first VM to a second storage system over the network, wherein the first host system is a separate system communicatively coupled to the first storage system.
20. The system of claim 19 , wherein the VM management server maintains VM configuration information of the plurality of VMs hosted in the plurality of host systems.
21. The system of claim 19 , wherein the consistent state of the first VM is generated based on the VM snapshot captured by the VMM.
22. The system of claim 19 , wherein the second storage system is a separate system with respect to the backup application server.
23. The system of claim 22 , wherein the one or more VM disk images associated with the consistent state of the first VM are disk snapshots stored at the first storage system.
24. The system of claim 23 , wherein the backup application server requests the VMM via the VM API to delete the VM snapshot taken after the disk snapshots have been backed up from the first storage system to the second storage system.
25. The system of claim 19 , wherein the first storage system sends only segments of the requested VM images that have not been stored in the second storage system.
26. The system of claim 19 , wherein the second storage system invokes a deduplicated segment storage engine to store segments of the requested VM disk images that have not been stored in the second storage system.
27. The system of claim 19 , wherein the backup application server parses the received VM disk images associated with the first VM to determine information about files contained in the received VM disk images and saving the determined file information in a backup catalog.
